HybridFox need to be opened in another FireFox window. If you opened it as a tab of the same window as the UEC interface, just drag the tab title outside the current window, it will create a new window with HybridFox in it. Then, in HybridFox:

Click on the "Credentials" button

Fill "Account Name" with any string describing this account

Fill "AWS Access Key" with the value provided in UEC as "Query ID"

Fill "AWS Secret Key" with the value provided in UEC as "Secret Key"

Click on the "Add" button

Click on "Close"

you should now be all set.

Using HybridFox

The documentation for HybridFox is, for all other purposes, the same as the one provided for AWS. A few tabs will not however be functional in UEC as the services are not implemented:

Reserved Instances

Virtual Private Clouds

VPN Connections

Also, please note that what is referred to in AWS as "Availability Zones" matches what Eucalyptus defines as "Clusters." Typically, there is a cluster controller (eucalyptus-cc), a storage controller (eucalyptus-sc) and one or more node controller (eucalyptus-nc) per cluster.
